ELECTRIC CONDUCTOR.

-' Application filed May 27, 1918. Serial No. 236,747.

To all whom it may concern:

Be it known that I, PETER F. FREY, a citizen of the United States,residing at Niagara Falls, in the county of Niagara and State of NewYork, have invented new anduseful Improvements in Electric Conductors,of which the following 1s a specifica-j wall and the creepage of liquidtherealong may be prevented. I

A further ob ect is to provide a construction for storage batterieswhich Wlll be simple to assemble and disassemble and in-- expensive andeffectual in operation to pre vent the creepage ofelectrolyte from theinterior to the exterior of the cell along the cell posts.

Further objects will appear the tion proceeds.

The one figure of the drawing represents one embodiment of the presentinvention. The numeral 1 represents a wall. This wall may be one of theside walls or the cover of a storage battery and should be provided witha second threaded aperture. Extending through said aperture is anelectric conductor :2 which may be the cell post of a'storagebattery.Said cell post is screw descrip Snccificati bn 01 Letters Patent.

threaded as shown in the drawing. A bushing 3 provided, screw-threadedon both its internal and external diameters whereby to engage with thescrew-threaded conductor 2' and the screw-threaded portion of theWall 1. lVhen the bushing 3 is screwed in place between the conductor 2and the .wall 1 it should form such intimate contact with both electricof said members as to prevent the passage of liquid therebetween. Oneside of the bushing 3 should be provided with a plurality of holes t, 4,whereby a spanner wrench may be used for turning the bushmg 3.

In assembling the conductor 2 within the wall, the bushing 3 will bescrew-threaded into the wall at the same time that it is threaded on tothe/post 2. A tight joint will be provided which will 'efliectuallyprevent the passage of electrolyte. The bushing 3 may be readily removedwhenever necessary,

without the danger of breaking the cover.

One embodimentot the present invention has been described in detail.Many modifications will occur to those skilled in the art. It isintended in this patent to cover all such modifications that come Withinthe scope of the present invention as defined by the appended claim.

\Vhat I claim as new and desire to secure by Letters Patent of theUnited States is In storage battery construction having a cell postextending through the cover, a bushing screw-threaded to both the postand the cover and filling up the space between said post and said cover.

In witness whereof I have hereunto subscribed my name.

PETER F. FREY.
